Expert verdict
Brakes: 1.4× the national share
Brakes make up 29.6% of everything recorded on the 2005 BMW M6, against 20.9% nationally — 8.7 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 72.4% and this one manages 88.3% — 15.9 points ahead of what its age and mileage predict.
- Based on a small sample. 366 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

Where the BMW M6 is most common
Across all M6 model years on record (2005–2018): 2,264 BMW M6 cars tested in a recordable postcode area, across 4,150 tests. Birmingham (B) has the most, with 71 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most BMW M6 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2005 M6
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2005 M6
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 1.6% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the brake pipes 1.4% of tests
“rigid brake pipes excessively corroded”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
-
Check the tyre tread 1.4% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2005 M6 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £31–£88 — and 43% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

| Rigid brake pipes excessively corroded Brakes | Advisory | 15.6% | £80–180 |
| Pins and bushes pin or bush excessively worn Suspension | Advisory | 10.9% | £40–150 |
